INSEAL is a mechanical seal inserted inside of the filler pipe, combined with a specific venting architecture design that provides comfort and safety by improving the refueling quality of the fuel system: no more fuel spillage, “spit back” or premature shut off.

INSEAL is also an optimal solution for improving ORVR canister purge strategy for hybrid vehicles. A smaller canister and a smaller volume of hydrocarbons to be purged allow simplifying the definition of the purge strategy of the vehicle. By reducing the amount of hydrocarbons generated during refueling, carmakers can employ a less complex purge strategy coupled with a smaller carbon canister. A better purge strategy on the vehicle means cleaner exhaust gases and then cleaner mobility.

Thanks to INSEAL, the pressure undergone by the fuel tank shell is lower than with standard ORVR architecture. As a result the  amount of hydrocarbons pushed to the canister are reduced by 30%.

The fuel flow through the filler pipe is less turbulent, avoiding risks of premature shut off.

The seal provides a smooth shutoff, at the end of refueling, by creating a vacuum in the filler head and therefore eliminates any risk of fuel “spit back” or overfill.

INSEAL is a complete solution that can be adapted to any fuel system architecture for a safe and clean refueling experience.
